RECORD HOLDER FOR, TALKING MACHINES.

Application flled December 10, 1926. Serial No. 153,989.

My said invention relates to record holders or trays for talking machines, the ob e ct being to provide such a holder which will be adapted to support records of diflerent a diameters and hold them central on the tray regardless of their diameters; also one that will maintain said records in a fiat condition, preventing warping; and one wherein the surfaces of the records will be protected in use, all as will be hereinafter more fully describedand claimed.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar part-s,

l igure 1 is 'a plan view of the record holder of my improved construction,

Figure 2, a cross section through the same,

Figure 3, a detail cross section on the dotted line 33 in Figure 1 on an enlarged scale,

Figure at, a similar view on dotted hne 44 of Figure 1, v

Figure 5, a view showing a modified form of the tray, and

Figures 6 and7, sections through the same on line 6-6 and 77, respectively.

In-said drawings the portions marked 10 represent the base or main part of said record holder or tray and 11 a lining therefor of softer material upon which the record holder may rest.

The base 10 comprises a circular metal plate with its edge 12 turned upwardly slightly inclined or curved at the edge to ermit the ready insertion of the selecting gers, and inwardly, as shown most clearly posed plate. A centering boss or collar 13 is mounted in the center of said disk, its upper end being flush with the upper surface of the inturned edge 12 and of an exterior diameter to correspond substantially with the interior diameter of the usual central aperture in the records.

My said record holder or trayis especially designed for use with machines adapted to play a stack of records, where said records are superposed one upon the other in such a stack, but as will be readily understood is adapted for use for holding any record in any type of machine.

The lining 11 which covers the upper face or inner surface of the base or tray is preferably of cork, paper pulp, or some such softer material, having a slightly roughened or frictional surface to which the fiat undersurface of the record will adhere by friction, thus insuring that the record will turn with the holder or tray in the operation of the in added friction when playing under a needle and all tendency of record slip will be eliminated. This frictional contact is further enhanced by the fact that the tendency of the record to warp is obviated and a flat plane surface maintained. The frictional contact between the trays is sufficient so that they will turn as a stack.

The construction shown in Figures 5 and 6 is designed to adapt atray normally constructed for twelve inch records to receive and play ten inch records with a twelve inch setting of the needle and tone-arm. This is accomplished by inserting a ring 20 within the tray and within the inturned edge 12, the top face of said ring being slightly below the plane of the top face of said edge 12. Said ring 20 is formed with a lip 21 at one point which slightly overhangs the surface of a record placed within said ring. A groove 22 is formed in said ring 20 beginning at the starting position of the first groove of a twelve inch record, said groove passing in by one turn a spiral direction around the circumference of the ring so that its inner end will pass over lip 21 and drop onto the surface of the record beneath, di-

.either ten or twelve inch records.

rectly on the starting position of a ten inch record. It will be understood, of course, that said ring may be made integral with the tray, or, if preferred, it may be separate therefrom and inserted as shown. By this means the tray may be used for playing By such a scheme with rings of different width the same tray may be adapted to play records of any diameter. i

It will be obvious to those skilled in the art that various changes may be made in my device-without departing from the spirit of the invention, and I, therefore, do not limit myself to what is shown in the drawings and described in the specification, but only as vention, what I claim as new and desire to 20' set forthin the appended claims.

Having thus fully described my said insecure by Letters Patent, is:'

1. A record holder for talking machines comprising a tray with an inturned edge,

the top surface of which is in a plane slightly above the plane of a record disk placed thereon, and a ring inserted within said edge to reduce the holding diameter of the tray,

said ring being formed with a groove exlip projecting over its inner edge, and with avgroove extending in a spiral direction across sald ring beg nning at the initial playing position of a larger record and pass ing across said lip, substantially as set forth.

3. A record holder for talking machines comprising a support having a rim of greater thickness than the thickness of a record to be supported and means removably mounted within said rim to reduce the holding diameter of the support, substantially as set forth. 1

4. A device for supporting a centrally perforated" disk record upon a talking machine comprisin' a substantially fiat body provided wit a rim'of greater thickness than the thickness of the record to be supported,

a frictional lining upon the upper surface of said body a centering device-for engaging the'perf record, and means disposed within the confine of said 'rim for reducin the record holding portion of the body or-accommodating a record of a smaller size, substantially as'set'forth.

5. A device for'supporting a central-1y er forated disk record'upon a talking mac ine vided with a rim of greater thickness than the thickness of the record to be supported, a frictional lining upon the upper surface of said body, a centering device for engaging the perforation in the center of the record, and means disposed within theconfine'of said rim for reducing the record holding portion of the body for accommodating a record of a smaller size, said means having a lip disposed in a position to permit a reproducing needle to slide therefrom onto the oration in the center of the" comprising a substantially flat body pro-' I surface of the record, substantially as set forth. I

6. A device for supporting a centrally perforated disk record upon a talking machine comprising 7 a substantially flat body provided with a rim of greater thickness than the thickness of the record to be supported, a frictional lining upon the uppersurface of said body, a centering device for engaging the perforation in the center of the record,

and means disposed within the confineof the record holding portion of the body orlaccommodatin a said rim for reducin record of a smaller size, said means having a li disposed in a position to permit a repro ucing needle to slide therefrom onto the surface of the record, said inserted means being provided with a spiral groove extendin from its outer edge to said lip, substantia ly as set forth.

In witness whereof I have hereunto set my hand at Waynesboro, Pennsylvania, this 22d day of November, A. D.-nineteen hundred and twenty-six.
